Identify early dysfunction to preserve retinal reserve

Summary: Your eyes have a hidden superpower called "retinal reserve." This means your eyes can keep your vision perfectly clear even if they are starting to get sick or damaged. Because the back of your eye (the retina) works so hard and uses so much energy, it can get stressed easily.

The problem is that many people wait until their vision gets blurry to see a doctor. By that time, the hidden reserve is all used up, and the damage might be permanent.

Eye doctors are now learning that they shouldn't just wait to see physical damage on eye scans. They need to test how well the eye functions early on—like checking how it adjusts to the dark. Catching these hidden problems early, before your vision actually changes, can help save your sight for a much longer time.
